NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
breakdown because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also use
the procedure in the printed matter which is included in the repair
parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick-
up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
If the optical pick-up block is defective, please replace the whole
optical pick-up block.
Never turn the semi-fixed resistor located at the side of optical pick-
up block.
SERVICE NOTES
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.

•UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size.)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
•Unleaded solder melts at a temperature about 40°C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350°C.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
•Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
•Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

ou au câble d’alimentation de l’amplificateur
d’antenne
Remarques
• Il n’est pas nécessaire de raccorder ce câble s’il n’y a pas
d’antenne électrique ni d’amplificateur d’antenne, ou avec
une antenne télescopique manuelle.
• Si votre voiture est équipée d’une antenne FM/AM
intégrée dans la vitre arrière/latérale, voir « Remarques
sur les câbles de commande et d’alimentation ».
3Au niveau de AMP REMOTE IN de
l’amplificateur de puissance en option
Ce raccordement s’applique uniquement aux amplificateurs.
Le branchement de tout autre système risque
d’endommager l’appareil.
4À la borne +12V qui est alimentée quand la
clé de contact est sur la position accessoires
Remarques
• S’il n’y a pas de position accessoires, raccordez la borne
d’alimentation (batterie) +12 V qui est alimentée en
permanence.
Raccordez d’abord le câble de mise à la masse noir à un
point métallique du véhicule.
• Si votre voiture est équipée d’une antenne FM/AM
intégrée dans la vitre arrière/latérale, voir « Remarques
sur les câbles de commande et d’alimentation ».
5À la borne +12V qui est alimentée en
permanence
Raccordez d’abord le câble de mise à la masse noir à un
point métallique du véhicule.
Connection diagram
1To a metal surface of the car
First connect the black ground (earth) lead, then connect the
yellow and red power supply leads.
2To the power antenna (aerial) control lead or
power supply lead of antenna (aerial) booster
Notes
• It is not necessary to connect this lead if there is no power
antenna (aerial) or antenna (aerial) booster, or with a
manually-operated telescopic antenna (aerial).
• When your car has a built-in FM/AM antenna (aerial) in
the rear/side glass, see “Notes on the control and power
supply leads.”
3To AMP REMOTE IN of an optional power
amplifier
This connection is only for amplifiers.Connecting any other
system may damage the unit.
4To the +12V power terminal which is
energized in the accessory position of the
ignition switch
Notes
• If there is no accessory position, connect to the +12 V
power (battery) terminal which is energized at all times.
Be sure to connect the black ground (earth) lead to a
metal surface of the car first.
• When your car has a built-in FM/AM antenna (aerial) in
the rear/side glass, see “Notes on the control and power
supply leads.”
5To the +12V power terminal which is
energized at all times
Be sure to connect the black ground (earth) lead to a metal
surface of the car first.
Remarques sur les câbles de commande et d’alimentation
• Le câble de commande d’antenne électrique (bleu) fournit une
alimentation de + 12 V CC lorsque vous mettez la radio sous
tension.
• Lorsque votre voiture est équipée d’une antenne FM/AM
intégrée dans la vitre arrière/latérale, raccordez le câble de
commande d’antenne (bleu) ou le câble d’alimentation des
accessoires (rouge) à la borne d’alimentation de l’amplificateur
d’antenne existant.Pour plus de détails, consultez votre
détaillant.
• Une antenne électrique sans boîtier de relais ne peut pas être
utilisée avec cet appareil.
Raccordement pour la conservation de la mémoire

de la mémoire est alimenté en permanence même si la clé de
contact est sur la position d’arrêt.
Remarques sur le raccordement des haut-parleurs
• Avant de raccorder les haut-parleurs, mettez l’appareil hors
tension.
• Utilisez des haut-parleurs ayant une impédance de 4 à 8 ohms
avec une capacité électrique adéquate pour éviter de les
endommager.
• Ne raccordez pas les bornes du système de haut-parleurs au
châssis de la voiture et ne raccordez pas les bornes du haut-
parleur droit à celles du haut-parleur gauche.
• Ne raccordez pas le câble de mise à la masse de cet appareil
à la borne négative (–) du haut-parleur.
• N’essayez pas de raccorder les haut-parleurs en parallèle.
• Raccordez uniquement des haut-parleurs passifs. Le
raccordement de haut-parleurs actifs (avec amplificateurs
intégrés) aux bornes des haut-parleurs peut endommager
l’appareil.
• Pour éviter tout problème de fonctionnement, n’utilisez pas les
câbles des haut-parleurs intégrés installés dans votre voiture si
l’appareil partage un câble négatif commun (–) pour les haut-
parleurs droit et gauche.
• Ne raccordez pas entre eux les cordons des haut-parleurs de
l’appareil.
Remarque sur le raccordement
Si les haut-parleurs ne sont pas raccordés correctement, le
message « FAILURE » s’affiche.Dans ce cas, assurez-vous que
les haut-parleurs sont bien raccordés.
Notes on the control and power supply leads
